Discrete Interval Sampler

Model 425 is a stainless steel sampler, with LDPE tubing mounted on a convenient reel. Discrete interval sampling is ideal for obtaining truly representative water samples from below floating product layers, or for obtaining samples of the product itself. Can also be used to profile open bodies of water and boreholes, and to collect samples from distinct levels or points of inflow. The Discrete Interval Sampler is a passive sampler, that is pressurized when lowered and upon retrieval, to prevent water mixing at different levels. The operation principles allow for zero purge volumes during operation.
